How to Choose the Right Dumbbells
Dumbbells are the most versatile free weight training tool. From dumbbell presses and flyes to curls and rows, they enable full-body workouts and are essential for home gyms, personal training studios, and commercial facilities alike.
At UCHINOGYM, we carry REP Fitness urethane dumbbells, hex dumbbells, and adjustable dumbbells — all sold as authorized imports with full manufacturer warranty.
3 Key Factors When Choosing Dumbbells
① Fixed vs Adjustable
Fixed dumbbells require no weight changes between sets, making them ideal for high-traffic commercial gyms. Adjustable dumbbells replace an entire dumbbell rack with a single pair — perfect for space-limited home gyms and personal training studios.
② Coating & Shape
Urethane-coated dumbbells offer superior durability and protect floors — the standard for commercial gyms. Hex-shaped heads prevent rolling for added safety. Round urethane dumbbells combine a premium look with excellent long-term durability.
③ Weight Range
Consider whether you need light weights for rehab and warm-up, or a full range up to heavy loads. REP Fitness urethane dumbbells are available from 2.5 kg to 60 kg in 2.5 kg increments.
